Improved carpet-stretcher



UNITED STATES PATENT OEEIGE.

JOHN B. GBEENALGH, OF PROVIDENCE, RHODE ISLAND.

IM PROVED CARPET-STRETCH ER.

Specification forming part of Letters Patent No. 85,925, dated January 19, 1869.

To all whom t may concern:

.Be it known that I, JOHN B. GREENALGH, of the city and county of Providence, in the State of Rhode Island, have invented a cervtain novel and useful Carpet-Stretcher; and I do hereby declare the following specification,

' taken in connection with the drawings furattached to the rear of the toothed foot by a double joint. D D represent teeth inserted into the metal forming the foot.

The operation of the stretcher is as follows: The teeth are set firmly into the carpet near the edge of that portion about to be laid. The lower part of the lever B is then driven slightly into the floor beyond the edge of the carpet. By a forward movement of the upper end of the lever the stretcher-beam A is carried forward with the carpet. Should the slack thus taken up be insufficient, the check-pawl C is dropped, so that when the lever B is permitted to move backward it becomes a check to the backward movement of the carpet, permitting another movement forward of the lever B, and so on until the edge of the carpet will be sufficiently advanced to secure a smooth surface, so much desired.

The stretcher may most satisfactorily be made of cast metal, as the parts would possess requisite strength and be comparatively inexpensive. The teeth should, of course, bc made of ne iron or steel wire, set into molds land cast into the foot of the stretcher-beam.

Carpet-stretchers combining the lever B with the stretcher-beam A have been made before, in connection with a pawl extending from the lever B back to a rack upon the stretcher-beam. Such stretchers, however, are capable of but a limited movement, and not suicient to stretch a carpet on alargc room.

To produce a carpet-stretcher simple in its construction, of convenient size, yet possessing a capacity to stretch acarpct to any usuallyrequired extent, myinvention is intended, and practically accomplishes.

I therefore claim as new, and desire to secure by Letters Patent, in a carpet-stretcher 1. The check-pawl O, with its double or single joint hinged to the toothed foot, and arranged substantially as described.

2. The combination of the check-pawl C, the stretcher-beam A, with its toothed foot, and the lever B, arranged and operating substantially as described.

JOHN B. GREENALGH.
